I hope you are considering what you read in this reflector as regards those
two subjects. This what I did for my two towers:
1. 22' mast pipes: With gin pole put them inside the tower when I had about
30 ft. of tower stacked then raised the mast via my gin pole after all was
stacked.
2. Tramming; Yes, only way to fly. I trammed up 2 yagis on each tower. If
you tie your tram line on to the mast, "high"; Be cautious you don't bend
your mast pipe when stretching it out, with a vehicle. I 'may have' bent my
one mast pipe a tad as I had to use a compensating mount underbeath my
Create rotor to take out a 'hang-up' when rotating. Depending upon
how-much you are lifting you may want to consider a back-up guy for the
tram line.
I read that some hook their tram line right at the top of the tower to
avoid the pull on the mast, and then man-handle the yagi up where you want it.
It sure was nice, though to tram up the yagi right where you want to clamp
it to the mast.
Now: That thread has come full circle back to "Towertalk"!
